V2O5 has a high theoretical capacity of 440 mAh g(-1) as cathode materials for lithium ion batteries. However, the poor conductivity may affect the lithiation/delithiation behavior greatly. This study effectively solves the poor conductivity and lithium ion migration rate of V2O5. Nitrogen-doped carbon-coated V2O5 composites (NCNPs-V2O5) are synthesized via an organic solvent assisted in situ hydrothermal growth method. Owing to the NCNPs and their novel 3D flower structure, the as-prepared NCNPs-V2O5 exhibited remarkable electrochemical performance as cathode material of lithium ion battery.
